Oral Care in ICU Mechanical Ventilation Patients and Associated Pneumonia: A Literature Review

Abstract

Background: Poor oral health can lead to hospital-acquired pneumonia, a serious condition that can prolong patient care and increase the risk of mortality. The bacteria found in the oral cavity of patients with periodontal disease can be particularly harmful if inhaled into the lungs. Patients who are on mechanical ventilation are at an increased risk of developing aspiration pneumonia. Objective: to investigate the effect of oral care on ventilation associated pneumonia (VAP) and various types of such care. Methods: This review article is performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature exploration was done in PubMed, Embase, and Web of Science databases for articles published between 2011 and 2023. The search words were "Mechanical ventilation, intubation, pneumonia, dental care, oral care and ICU ". Results: A total of 21 studies were included, the studies were randomized controlled trials (RCTs) or quasi-RCTs and observational studies. Twice-daily oral care with tooth brushing using purified water can significantly reduce the incidence of VAP. Oral care with chlorhexidine and brushing, as well as enhanced oral care, can also be effective in reducing the incidence of VAP. Improved education and implementation of oral care protocols with 0.12% chlorhexidine solution can significantly reduce the incidence of VAP. Conclusions: The review concludes that good oral hygiene, especially twice-daily oral care with tooth brushing using purified water, can significantly reduce the incidence of VAP in mechanically ventilated patients.
